Hiring hall

[3] In building and construction trade,[1] due to the scattered nature of workplaces and bidding projects, both the employees and employers have a symbiotic need for steady employment and skilled labor respectively, which are facilitated in the various craft union controlled hiring halls.

[3] Employment in the film industry in the 1950s became more differentiated, due to anti-trust rulings, e.g United States v. Paramount Pictures which divested studios from exclusive contracts with specific theaters.

Film production itself became heavily distributed, with post-production, editing being fulfilled by different contracts rather than centrally.

Recruiting talent was no longer based on employment in a single firm, but through a roster that measured seniority within the industry.

These rosters were maintained by talent guilds and unions such as IATSE, SAG-AFTRA,[4] Actors' Equity Association.
